Mai-Kai's cocktail menu is ominous. The shrunken skull is "dangerous and deadly." The Bora Bora is an "adventurous challenge," and the 151 swizzle is "only for the sturdy." Although all are tasty concoctions that will have you slurring after a few sips, the real standout is the aptly named black magic. This potent snifterful of dark rums, lime juice, coffee, and other mystery ingredients is frighteningly refreshing and surprisingly complex. From the first sip, the flavor of coffee lingers on the taste buds without overwhelming them. After a few gulps, the stinging jab of various rums subsides, leaving the gut warm and tongue loose. If the $14 price tag is a turnoff, just get to the bar during a daily happy hour, when all drinks are half-priced.
